Brother MFC-J3940DW Driver Download

Brother MFC-J3940DW Driver gives the computer the software link it needs to send jobs to the printer correctly. Print, scan, copy, and fax functions rely on that communication once setup is complete. A computer can use either the network connection or a direct wired link, depending on how the machine is installed. The driver also passes page and output settings to the correct printer function instead of sending them as undifferentiated commands.

Brother MFC-J3940DW Specifications

The Brother MFC-J3940DW is an A3 colour inkjet multifunction machine that prints, scans, copies, and faxes. Printing comes from a piezo inkjet head using four ink colours, backed by 256 MB of memory. A 3.5-inch colour touchscreen sits on the control panel for settings and status information. For multi-page originals, the 50-sheet ADF can feed one- or two-sided documents automatically instead of requiring each page to be placed on the scanner glass.

Black and colour documents print at up to 28 ipm. From a ready state, the first mono page can appear in about 4.4 seconds; colour takes roughly 4.6 seconds. Print resolution goes as high as 1200 × 4800 dpi. Automatic duplex printing remains available on sheets up to A3, which avoids manual page turning for larger two-sided documents. The flatbed scans at up to 1200 × 2400 dpi optically. Originals passing through the ADF are scanned at up to 600 × 600 dpi.

Two front paper trays hold 250 sheets each. A separate 100-sheet multipurpose tray gives the machine another feed for different media or long plain-paper jobs. Standard sheets can range from small A6 and photo sizes to Legal, Ledger, and A3. Envelopes also fit the listed feeds. For banner-length paper, the multipurpose tray takes a single sheet up to 1200 mm long. Printed A4 or Letter pages collect in the 100-sheet output tray, so its capacity is lower than the combined input capacity.

A nearby computer can use the Hi-Speed USB 2.0 connection, and Fast Ethernet is available for a wired network. Wireless printing can travel through the local Wi-Fi network instead. Wi-Fi Direct creates a direct wireless link when a router connection is not wanted, and NFC hardware is built in for compatible devices. AirPrint and Mopria provide additional mobile-printing routes. With the machine measuring 576 × 477 × 375 mm and weighing about 23.4 kg, it needs more desk space than a compact A4 printer. Brother lists power consumption at approximately 29 watts during copying.
